International Water-Guard Industries Inc. (IWG) is the world’s dominant provider of flight-certified water treatment units and has grown to supply a variety of specialized aircraft water system components. Today, more than 2,000 of IWG’s flight-certified units are shielding aircraft passengers and crew around the world from waterborne disease.

IWG currently produces four models: the IWG-A6, IWG-A4, NPS-A6, and NPS-A3, for water flow rates from 4 USgpm down to 1USgpm. (multiples may be used for higher flow rates) It is still possible to order the original NPS-A2, although this product is effectively retired.

The IWG series are our latest designs, incorporating enhanced control and monitoring. The NPS series are the current standard on many top of the line business jets. All units use ultraviolet light disinfection to eliminate harmful micro-organisms, and are benchmarked to the National Sanitation Foundation’s highest irradiation threshold (Standard 55, Class A – 40mw/ cm2).

In addition to our flagship line of water treatment units, IWG is now pleased to offer the ES series of Aircraft Instant Water Heater. These products are optimized for high flow requirements of hot water, as may typically be needed in aircraft showers and VIP galleys, and have been supplied to the aerospace industry for more than 10 years.

For enhanced water system performance, IWG offers a line of high reliability water pumps. Various models may be used as either the primary pressure source in a potable water system, or as a booster pump for special applications.
